I figured my core is what has benefited the most from doing this for the past 8 months or whatever it has been. I am able to do Red Hot Core pretty easily. I made it to 5 on those things and by #6 my back was spasming and my abs felt like there was a semi truck sitting on top of them.
The fact that he does 50 is obscene. New challenge accepted!
